I believe that I wasn't too clear on my last post, so let me offer a scenario. If I had # 12/2 NM cable in a box (black and white) for a single pole switch, I have to identify the white conductor as an ungrounded conductor. Am I suppose to phase the entire length of wire or are a couple of wraps sufficient? Code Ref. please.
One wrap around the conductor is all that's required. It's funny because for other than a switch loop a stripe along the conductor edge made with the side of a Sharpie does not satisfy the wording of the NEC.
I am confused, where does it say I cannot use a Sharpie to reidentify the conductor? I am sure it is plain as day, but I am missing it.
200.7(C) Circuits of 50 Volts or More. The use of insulation that is white or gray or that has three continuous white stripes for other than a grounded conductor for circuits of 50 volts or more shall be permitted only as in (1) through (3).
(1) If part of a cable assembly and where the insulation is permanently reidentified to indicate its use as an ungrounded conductor, by painting or other effective means at its termination, and at each location where the conductor is visible and accessible. Identification shall encircle the insulation and shall be a color other than white, gray, or green.
Just a technicality but the requirement for other than switch loops is for the re-identification to encircle the conductor. So the stripe down the side that we all do with the sharpie is NG. :roll:
